3 LOADING} APPARATUS.

I a citizen of the United States, residing at Cleveland, inthe county ofCuyahoga and State of Ohio, have invented acertain new and usefulImprovement in Loading Appareins, of which the following is a full,clear,

and exact description.

"This invention relates to loading apparatus and particularly to theso-called trimmers which are utilized forloa-ding vessels with coal andlike uaterial'wliicli can be discharged.through a chute or spout'intothe hold of the vessel. I I

The object of the'invcntion is to provide a trimmer or loadingapparatus,which permits the material to 'be distributed uniformly and evenly over;the hold of the vessel or other nemloer'to be lo aded, 'and which can beeasily operated 'andis under perfect control of the. operator so thatthe discharge ing member can be shifted about in all directions and toall required positions to secure the desired uniform distribution.

Aefurther' object is to provide a trimmer which is more efii'cient intine required to loada vessel, in manner of-loadin'g, and ease ofoperatiomandis less expensive to install and operate than the apparatusused heretofore.v I

These and other objects are attained by ,my invention which in thepreferred eml'iodirnent. includesa hopper which may be supported ona'frame of a car dumping ap-v paratusand. has attached-to the lower endthereof a 'chute which is designed to be low- 'ered into'theholderhatchway of a. vessel,- and preferably-consists of joints or sectionsconnected-and movable in such a manner "that-the discharge. end-hf thechute'may be shifted about so as to: discharge the material Which isdumped into the hopper in any. 'part ofthehatchway. i 1' YPreiEerably,the hopper I isrplvotally connected to the supporting frame so that thehopper, as well as theclischarging and'dis- Specification of LettersPatent, Application filed ma as, 1910.

and for operating the plunger will now be explained. The movements ofthe sections of the chute, of the plunger, and; of the hopper may becontrollechby an operator i 7 who may. be located at a suitable stationwhich may be supported in any suitable manner from the-'hopper,preferably directly over the vessel so that the operator can observe theaction of the trimmer and the-loading of the vessel, but this operatorsstation, I have not,shown, to avoid complicating the drawings anddescription.

To raise and lower or swing the entire chute with reference to thehopper, forwardly projecting arms 36 are provided at the-upper endof'the section 22, and these arms are connected by a .rod 37 to which isattached a cable '38 which passes about a drum 39 mounted on a shaftwhich may be supported in any suitable manner tromthe hopper, and maybeoperated by means of a motive device,su ch as an electric motor 40 andgearing which may bethrown into driving relation, therewith by means ofa clutch 41. To hold the chute in any desired position ';with referenceto the hopper a ratchet 42 maybe provided at one end of the drum. Thus,by turning this drum by means of the motor, the operation of which canbe controlled fromthe voperators station, the entire chute can be' swungabout the pivotal supporting rod 25 so as to swing the lower end of thechute. backwardlyon forwardly along the hatchway of the vessel.

The sections 23 and 2 tofthe chute may be turned horizontally orlaterallywith reference tot-he section 22 so as to swing the dischargeend of the chute across the hatch- Way by di iierentmechanisnis, but inthis case I have shown .thefollowing mechanism. At the upper end ofsection 23 of thechute is a sheave 43=which is engaged by two cables 44and 4.5 passing about the sheave in opposite directions and eachdead-ended thereon. These cables pass about suitable sheaves 46 and 47*which are supported on the front of the section 23 adjacent, the sheavee3, thence-about sheaves 48 which the chute constitute a '50 are turnedin the opposite direction b clutched thereto by a clutch 57.

are mounted upon the pivotalsupporting rod 25 between the ears on thehopper and on the section 22, and thence these cables pass in'oppositedirections about a pair of drums t9 and 50 mounted upon a shaft51, which may be 'driventhrough suitable gears by the motor 4.0previously. referred to. A suitable clutclihi which may be shifted bythe operator from his station is provided for forming or breaking thedriving connection between the-motor and the shaft 51. Vi hen this shaft51 and drums 49 and 50 are turned in one direction by the motor whichpreferably will be of the reversible type, the sheave 43, andconsequently the middle and lowermost sections 23 and 2% will be turnedin onedirection with reference to the section 22 and hopper, and-whenthis shaft 51 and drums 49 and I y the motor, the sections 23 and t-Willbe turned in the opposite direction.

The mechanism for raising and lowering the section 24 of the chute withreference to the section 23, and for operating the plunger will now beexplained. Extending between the'parallel side walls of the upper orrear portion of the section 24. and journaled in said side-walls insuitable bearings carried thereby is a short shaft 53 which is providedwith a bevel gear 54; normally loose 'on-the shaft, but-capable of beingclutched theretoby means of a clutch The shaft 53 is 'providedvalso witha spur gear 56 which is loose on the. shaft, but may be This gear isengaged and adapted to be driven by a gear 56 0f a motor 5.6. "The bevelgear m meshes with a bevel-gear 58' which is fixed to the lower end of athreaded shaft 1 5 which extends substantially vertically ali'ingtherear side of the middle section of the chute, the gear 58 and shaft 59being held in proper position relative to the gear 54 by means of abracket 60,- and this shaft 59 11!} engages a nut 61 which is pivotal'lysupported by a pair of ears 62.extending rearwardly from the middle"chute section 23. The pinion 56 meshes with a gear 63 which is mountedupon a shaft 64 extending between the 11s side walls of the rear part ofthe chute section 24 justabovethe plate 35 previously re- I ferred to.This gear 63 and a suitable wheel or disk 65 at the opposite end of theshaft 64are'provided with eccentrically arranged pins 66 which areconnected by links 67 to a. pair of arms 68 arranged on opposite sidesof the chute, these arms beingpivotally supported at their upper endsupon the pivotal support-ing rod 31 for the chute section '24, 325 andbeing connected at their lower ends to links 69. the rear ends of whichare connected by a rod 70 passing through the rear part of the plunger34 and passing loosely through elongated slots in the opposite side 13a5 other; or} throw.i'1 i'gfitheIn both kiniisimulta- :65 tic-swung froma substantially vertical fpol 10 gerwill be ieciprocatedjbythe-mechanism? previously described.
